This research study is studying racial and genetic biomarkers of response in tissue samples from patients with endometrial cancer. Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. DNA analysis of tumor tissue may also help doctors predict how well patients will respond to treatment.

Primary Outcome Measures:
  • Clinicopathologic and demographic characteristics: characteristics: self-reported race, stage, age, race, parity, body-mass index, stage, grade, depth of invasion, lymph-vascular space invasion, and metastasis [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Overall survival [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Progression-free survival [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Proportion of genetic background that is of African-American descent [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Racial genetic admixture score, summarized by race and other clinicopathologic variables [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Estimated Enrollment: 243
Study Start Date: January 2100
Estimated Primary Completion Date: January 2100 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Basic science (DNA analysis)
DNA from archived frozen normal tissue samples is genotyped for the ancestry informative markers. Clinicopathological and demographic characteristics associated with each sample are also collected.
Other: Laboratory Biomarker Analysis
Correlative studies
Other: Study of Socioeconomic and Demographic Variables

Detailed Description:


I. To identify racial categorization as the proportion of genetic background of African-American or European-American women with endometrioid endometrial cancer (EEC).

II. To evaluate the association of racial genetic admixture with clinicopathologic variables and outcomes.


I. To compare the concordance between racial genetic admixture and self-designated race categorization.

OUTLINE: This is a multicenter study. Patients are stratified by race (African-American vs European-American) and disease stage (I vs II vs III vs IV).

DNA from archived frozen normal tissue samples is genotyped for the ancestry informative markers. Clinicopathological and demographic characteristics associated with each sample are also collected.
